A perfectly matched layer for the absorption of electromagnetic waves. (English) Zbl 0814.65129

An absorbing layer that does not activate any reflection at an interface with first vacuum is described and then applied to build a new technique of free-space simulation for solving an unbounded electromagnetic problem with the finite difference time-domain method. This technique appears to be more attractive than the earlier techniques of free-space simulation.
